Abstract

The invention provides a verification method and system for intelligent contract transactions in a block chain, a computer device and a computer readable storage medium, and relates to the technical field of data processing. The method comprises the steps of adding identifiers of transaction types in the intelligent contract transactions when a transaction sending node broadcasts a plurality of intelligent contract transactions in a block; a block generation node executing the intelligent contract transaction according to the transaction type identifiers of the intelligent contract transactions; broadcasting the block after the executed intelligent contract transactions are packaged into the block; a verification node receiving the block and executing the intelligent contract transactionsaccording to the transaction type identifiers of the intelligent contract transactions to obtain the final state of the block; the verification node comparing and verifying the final state of the block with the post-transaction state recorded in the block, and the block being verified to pass when the final state of the block is consistent with the post-transaction state recorded in the block. According to the invention, the verification efficiency of the block is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to the verification technology of the blockchain application system, specifically a verification method for smart contract transactions in the blockchain, a verification system for smart contract transactions in the blockchain, and computer equipment and computer readable storage media. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, according to the consensus mechanism of the blockchain, on the distributed network of the blockchain, each node broadcasts the transactions issued by itself, and the block packaging nodes (also called mining nodes) selected by the consensus collect the transactions on the network, according to Execute the transaction in ...
